While most fans prefer Bonnie over April, at least we got to see April's sister and adopted niece in the episode "Race for Life". Whereas Bonnie's relatives were only mentioned, but never appeared on screen. In "Sky Knight", Bonnie too has a sister as she was en route to her wedding when her plane was hijacked. And in "Just My Bill", she mentions slashing her wrist to convince her dad she couldn't stand the sight of blood. Plus while Bonnie dealt with KARR, April dealt with Garthe Knight.
I've always had a weakness for Authentic Strawberry Blondes/Redheads. Irish/Russian mix girls. To April should have stayed on in season 3 and 4 and competed with Bonnie over KITTs attention. That would have been a fun twist.
If she had replaced Patricia McPherson (who played the character of Bonnie) in season 2, when the latter returned to the series at the beginning of season 3, the character of April has disappeared without being provided with any explanation on what it becomes ! Why did the writers and producers never find it useful to give the answer (either in the first episode of season 3 or in one of the other episodes of the series) ?
Patricia McPherson got replaced because the studio had a more "sexy" character for the mechanic role in mind. (Hilarious if you ask me, Knight Rider is no Playboy Series) besides, what is so bad in ms. Pherson. The fans and viewers didnt like that and so Patricia came back in season 3. The replacement is explained that Bonnie worked at an university for a year.
According to some sources, David Hasselhoff would not have appreciated that Patricia McPherson (who played Bonnie Barstow) be replaced by Rebecca Holden in the second season and that there would have been a disagreement between them. This is why he would have pressed the producers to have the character of Bonnie return to the series during the following season. Do you know more about it ?
She's trying so hard not to laugh in the scene with garth knight (From 2.43 onwards) especially when she said 'mirror'. Must've been the fake beard on Michael knight 😜 The production team must've been out of spare film or they would have had a re-take ☺
